Lubrication System (03.02)
Description
The engine uses a wet sump lubrication system.
Oil is drawn from the sump via an oil strainer and pick-up tube to the crankshaft driven oil pump. Pressure from the oil pump is limited by a built in oil pressure relief valve. Pressurised oil then flows from the left side of the engine through a filter and cooler then back into the engine main oil gallery.
Oil pressure at the re-entry point is approximately 60 psi with the engine hot and should reach at least 100 psi when cold.
